LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 355,408, dated January 4, 1887.

Application filed June 1, 1886. Serial No. 203,775. No model.)

' To all whom it may concern.-

the application and removal of the storm- Fig. 1.

sash, commonly applied during the winter season to the window-casing outside of the ordinary sash.

My hinge is designed more particularly for use at the lower end of the blind, the upper end of which may be sustained by a hinge of any ordinary or approved construction.

In the accompanying drawings, Figure 1 is a perspective view of the two parts of my hinge separated from each other. Figs. 2 and 3 are respectively a face view and a lower end view of the hingein its closedposition. Figs. 4 and 5 are respectively an outside face view and a lower end View of a hinge in its open position.

Referring to the drawings, my hinge consists of two parts, A and B, each cast complete in one'piece, of the form represented in The leaf A, which is designed for attachment to the wall or windowcasing, consists of a flat plate adapted for attachment to the outer face of its support, and provided with a projecting horizontal ribfa, having therethrough a vertical eye or opening, b, and at the rear edge horizontally-projecting lips c c, which are arranged in such relation with each other as to leave a vertical opening between them to seat the opposite leaf, as presently described. It will be perceived that the opening 12 is of a narrow flat form at the forward side'of the leaf, but enlarged to a circular form at the rear.

The leaf B consists of a flat plateprovided with an outwardly and downwardly projecting pintle, d, flattened on its side face, with a depending lip, e. The pintle dis passed downwardly through theeye b, and when the hinge is closed'the pintle is held by the weight of the blind at the rear or large end of the eye, as shown in 'Figs.2 and 3. As the blind is opened the pintle revolves in the large end of the slot until the opening movement is completed. During this movementthe lip eis carried to a position opposite the space between the lugs c c, whereupon the weight of-the blind will cause the outer leaf to swing inward, so that the flattened pintle will enter the flattened portion of the eye and the lip e engage between the studs 0 o, as shown in Figs. land 5. By this interlocking action the swinging leaf and the blind are secured iigidly in position, so that the closing of the blind is impossible.

It is to be noted asa peculiarity of my hinge that its parts interlock at. two points widely separated from each other, whereby it is held with a security not attainable in those blinds which rely simplyon a locking action of the pintle or a shoulder on the end of the pintle. In order to unlock the hinge, it is only necessary to push the lower end of the blind outward in the direction indicated by the arrow in Figs. 4 and 5, the effect of which is to disengage the lip e and carry the pintle into the widened end of the eye, so therein.

The essence of my invention resides in the employment of a flattened pintle in combina tion with an eye having one side enlarged to permit the application of the pintle, and the other side restricted in width to embrace and hold the same, and in the provision of surfaces at a distance from the pintle adapted to interlock by a, horizontal movement of the blind; and it is manifest that the form and configuration of these parts may be variously modified without affecting their mode of action that it may turn or passing beyond the scope of my invention.

Having thus described my invention, what I claim is 1. In a blind-hinge, the leaf provided with the'eye enlarged at one side, in combination with the leaf having the flattened pintle adapted to revolve in the enlarged side of the eye, but look firmly in the opposite side of the same, substantially as described.

'2; In a'blind-hinge, the leaf provided with the eye elongated horizontally, and shoulders In testimony whereof I hereunto set my hand 0 c at the outer edge, in combination with the this 27th day of March, 1886, in the presence of leaf provided with the pintle and with the lip two attesting witnesses. e, substantially as described. 5 3. In ablind-hinge, the leaf A, having the EDWVARD MORTON NEWCOMB.
